US Classification:

Abstract:

An airtight container, having two separated compartments, including an inlet to the first compartment and a flexible, gravel pick-up tube attached to the inlet. A cyclone separator is mounted on the second compartment with its separated particle outlet discharging into the second compartment. A connecting conduit connects the outlet of the first compartment with the inlet of the cyclone, so that the first compartment is a separator for gravel and dust and the second compartment is a dust container for the cyclone. A separate, high capacity air pump has its inlet connected to the cyclone's clean air outlet causing a flow of air through the unit for picking up gravel and dust through the flexible tube. For convenience the containers may be mounted on a truck, and both containers are unloaded through a common, sealable gate at the lower portion of the containers.
